Know More About Wire Drawing Machine and Dies

From thousands of years, wire is being manufactured by different types of methods. The manufacturing of wire is quite simple, but requires a higher degree of perfection. Earlier, wire are extruded while using strip & block twisting method, cranked pulling technique and hand pulling procedures.

Wire Drawing Machine

Each method has their own sets of merits and demerits. Today, different specifications of Wire Drawing Dies are used for making wire in order to achieve better quality and uniform volume.

Wire Drawing Machine manufacturers have presented various types of configuration that are used for drawing different types of wire. Standard wire drawing dies, TC wire drawing dies, PCD wire drawing are some to mention. Depending upon the application, these dies are used. For instance, single crystal diamond dies are used for achieving very fine drawing. Cast steel dies are used for drawing hot wire and tungsten carbide dies are used for steel wire drawing.

Wire Drawing Dies

Dies are employed for guiding the wire for entering, moving through and existing bunching and stranding machines. Therefore, dies are placed in a steel casing for backing the die and allowing easy die change. An angle of 6-15° is usually kept in dies with each die having at least 2 different angles, one is entering angle and other is approaching angle.

The procedure of wire drawing involves hammering, filing, rolling and swagging of wire before feeding it to drawing dies for diameter reduction. Multiple drawings, through a smaller diameter of dies, are needed to achieve a desired diameter of wire and uniform volume.

Materials use for making these wire drawing dies

• Tungsten Carbide


• Natural Diamonds


• Synthetic Single Crystal


• Poly Crystal Diamonds

Over the years, the applications of wire have increased to a massive level. Which demands maintaining a high degree of quality and safety standards. As when it comes to meeting the broad needs of industries, safety and durability are the parameters of concern for most buyers. There is a great need of mature technology with advanced machines to control even minute details while manufacturing wires.

Importance of Scaffolding In Construction

The term scaffolding is sometimes also referred to as staging or simply as a scaffold and is done by using innumerable methods and materials such as an acrospan, adjustable jack, cross brace, base jack, deck plate, aluminum form-work and many more. Scaffolding is used universally, with application areas expanding to almost all segments of the construction and maintenance sectors.

Scaffolding

The earliest reference to scaffolding is said to date back over 17000 years, with the discovery of sockets in the walls around the paleolithic cave paintings which seemed to indicate that a scaffold system was used for painting the ceiling. Another reference dates to 5th century B.C, the Berlin Foundry Cup also indicated staging in ancient Greece.

Coming to the modern era, a notable reference is the usage of staging during the reconstruction of the Buckingham Palace in the year 1913. Further advancements in metallurgy during the 20th century, with the usage of tubular steel water pipes, instead of timber poles ensured improvements in the structural stability of scaffolds.

Various Types of Scaffolding Used Worldwide Today

• Tube and coupler fitting components

• H-frame/facade modular system staging

• Prefabricated modular system scaffolding components

• Timber scaffolds

• Suspended staging

• Special scaffolding such as cantilever staging

• Wooden scaffolds 

• Needle scaffolds

• Mason's scaffolds

Components of Construction Scaffolding, Irrespective of which type of system is used, each one of them comprises of several components, some of which are,

• Forged Coupler – These are one of the fundamental components used to assemble tube and coupler scaffolding and can be used to create a diverse range of scaffolding structures

• Horizontal ledger – It is used to tie the staging to the structure

• Floor form panels – These are commonly used in the procedure of shuttering during the construction of floors

• Post shores – Simply put, these are load towers that serve as platform beams and provide side protection for working levels

• Beam bracket – Beam bracket is used to connect the scaffolding's beam to its frame.

The metal parts of the staging should be painted to resist corrosion while the wooden parts if any must never be painted, as painting them hides structural defects which can later prove fatal.

Pressure Switches - A Brief Overview

The proper functioning if large scale industrial machineries depend on a number of important factors and one of the most relevant of them all is the control part. It is here that Pressure Switches play a decisive role. It is through this kind of device that the power supply to hydraulic or pneumatic machinery is controlled.

This switch helps by applying by supplying or cutting off a particular amount of pressure to the input point and thus helps in switching on and switching off the electric supply. They are used for a number of purposes and this is the reason they have become so popular when it comes to the organizations that require a proper functioning of the hydraulic machineries.

How Pressure Switch are work?

The pressure switch is made of such types of components that will be able to put in the required amount of pressure that will help the machinery to work in the right manner without any malfunction. Some of the pressure switches can also control the flow of natural gas or a fluid.

Along with the main switch this device also includes necessary features that will be able to monitor the amount of pressure that has been put in, so that the user is able to judge the right amount of pressure without overriding the machine.
There is a particular level up to which the pressure switch will function normally and as soon as the normal level is crossed there will be some sort of an alarm to indicate the danger level. There are basically two types of pressure switches: –

• Pneumatic Pressure Switch:- The work of a Pneumatic pressure switch is to control a gas compressor’s functionality as well as the charge
  
  control mechanism that is present in cell phones and common for counting traffic and at gas stations.

• Hydraulic Pressure Switch:- This kind of pressure switch usually finds application in the automobiles for controlling the engine oil
  
  pressure hydraulic brake lines, transmission torque, etc. all these switches are various uses in automobiles.

What are Uses of Pressure Switches?

These switches are extremely beneficial as they play an important role in ensuring the proper functioning of machinery. By controlling the amount of pressure levels in that particular device or machine, the switches also help in preventing explosions and fatal accidents.

The alarm system which is an integral part of these switches makes it possible to keep a check on the level of pressure. Thus, apart from contributing in operational aspect, the switch is also an important component which takes care of the safety requirements.
